Evening Webby. The Eaton twin splits Lazydocker mentioned are a nightmare if you don't know how to use them properly which i don't. Most of them are 12 speed & you only use the clutch when pulling away or stopping. I can get by but tend to bounce around & play tunes with them. Fortunately they are pretty much extict nowadays...H reg ERF!!! Today most manual boxes are 3 on 3 or 4 on 4 range change with a split, ie 1234 flick the range switch & do it again so 1st becomes 5th, 2nd 6th etc. the split gives each gear a half gear so if a hill's approaching & you don't need to drop a whole gear you can pre select the split on another switch, change gear with your feet but not move the gear lever hence a 4 on 4 gives you 16 gears a 3 on 3 12 gears etc. Tunnie was right in saying given the weight they carry & the low rev band they need that many gears although he was being a cheeky young whippersnapper. I've met him a few times & he's not a bad lad really.
    Hope i hav'nt helped in the slightest, Guy.

Going back some years.... I never got the hang of them, managed, like you, with some crunching noises...

I think that is quite a good explanation of the gearbox system used by most trucks these days it is all to do with limited rev range and torque requirements.I have driven a Scania that was semi automatic in that it had a clutch that was only required when setting off or coming to a stop,all the gearchanges were done by the autobox. Yes I did stall it at the first set of traffic lights as I had a senior moment and forgot to press the clutch pedal

Evening Simon. The new Renaults we're getting now don't even have a clutch pedal....very bouncy when backing the trailer in a warehouse door at an angle. I've tried one but still in my old Globetrotter for now!

So are we talking all new trucks fully automatic then?  and I passed my test on a crash box, how times change....

They have a semi auto option like a powershift but it's a waste of time, give up, leave them in auto & let them get on with it.
   Bring back the Leyland Super Comet & the AEC Mandator!!!! 8-) Proper trucks!!!

I am with you on the classic stuff, but for real everyday work would you really want to drive a Mandator 9 hours a day, 5 or 6 days a week, and sleep in it....

[bluey]

Talking of Leyland (which I am loathe to do as I despise that badge), didn't the Roadtrain have a sequential 'box or something like that to aid downshifts?

[Varche]

Many many yeas ago, I hitched a lift on the M1 going North. (I told you it was a long time ago).

The lorry was a fairly new massive loaded artic. The driver had something like 16 gears to play with and I couldn't believe how many he actually used. Good part of my education and made me respect the job they do more.

Wasn't so impressed with him knocking it into neutral on the steep downhills AND overtaking vehicles. Must have been in the pre tacho days.

Speed limiter doesn't work when in neutral (apparentley ahem)

Eaton twin split is the best box ever!!!!! did around half a million miles using them on various ERF, SEDDON ATKINSON, and a few Leylend products, once you got the hang of it you just moved the lever up or down the shift pattern, made such an easyday of it!!
As to new trucks with fully auto boxes, I am definelty not a fan!!! apart from reversing being a pain cos they dont creep which is what you need to manoevre properly, they make you look like a complete amateur when hooking up!! because there is no creep you have to give it gas, fine so it shoots backwards to fast so you let the throttle off, then the weight of the trailer stops the bloody thing again so you have to give it gas, it dont move so more gas it dont move so more gas then it shoots bacwards and smashes onto the pin!!!! nightmare!!
then of course approaching a roundabout you slow down to see if its clear or not in a manual truck you selet the gear appropiate to the speed you are approaching the roundabout, if its clear or you can make it in time to not inconvenience the traffic you go!! not in an auto truck you dont!! blasted thing starts to pull then stops all drive whike it selects what it thinks is the right gear, realises its the wrong gear stops drive and selects another, this leaves you stuck halfway across the roundabout wth irate car drivers blowng the horn cos you stopped them on the roundabout!!! useless blasted auto sludgepumps!!!! then of course the fuel penalty is something else on a truck!!! may only be a mile a gallon, but take that over the average year where a truck will do 150,000 miles at around 7mpg and you can see that the fuel cost is ridiculous!!

Guessing over-all you don't like them 

I first came across these new fangled boxes on a trip snowboarding in the Alps, as the bus was pulling away could have sworn it was a manual, was only when walking past to get off realised it was an auto shifter.

The manual bus we were having a ding dong with on the way, had us out of the starting box toll booth, but we were heavily laden with snowboarding gear

Only one way to do a toll booth justice...

Ah, the old Aberdeen Overdrive! Lol! Please doi not try this on modern boxes as when neutral is selected on the move, the gearbox oil pump doesnt supply anywhere near enough oil around these big boxes! Got to agree on the Twin Splitter, once mastered a fantastic box to work with, made all the easier by not having to use a VERY heavy clutch, lol! Not a fan of most auto boxes in use at the moment, OK in a car but not for me in a lorry. Just recently was using a Merc 2550 V8 with auto box and it was a slug! So slow to move off it was hard to get out of some junctions when fully loaded, you had to time it so well to avoid blocking the road to oncoming traffic. And what a waste of a V8! Gutless! Give me a Scania V8 any day!

[Webby the Bear]

sorry guys, forgive my complete lack of knowledge....but....

hgv's can have an auto box??? as in a fully auto, D N R P??

 

[hoofing it]

lol that sounds complicated..... ok, why cant a hgv have a regular 5, 6 or 7 speed box?

Have you every driven a landrover where you have 5x low and 5x high gears =10 then on a truck you have 4low 4high and somtimes a spliter that gives you Half gears so you end up with a choice of 16 gears.
And it's good fun pulling away from traffic lights with only the unit leaving others behind
